Pratt & Whitney Canada has received type certification from Transport Canada and the European Aviation Safety Agency for the turboprop engine chosen to power the new ATR 600 Series, the PW127M. A derivative of the PW127F and PW127E engines that power today’s ATRs, the PW127M produces 5 percent more power than its predecessors. ATR now offers the new engines on any ATR 42-500 or 72-500 that rolls off its assembly lines as the company prepares the 600 Series to reach the market in the second half of 2010.

Designed to deliver better performance in hot and high conditions, the PW127M also improves the ATRs’ one-engine-out ceiling by about 1,000 feet. On the 600 Series, the extra power will help raise payload weights to address the demands of increasing passenger and baggage size. The ATR 72-600 will come with a standard mtow and zfw increase of 660 pounds, and ATR plans to offer optional weight increases of another 440 pounds.
